My toenails definitely grow faster than my fingernails. I must be one of the unusual people in this world because everything I read sayd that fingernails grow faster. I know for a fact that my toenails grow faster, but I have no idea why. I wish my fingernails would grow as fast as my toenails! I don't think that toenails grow faster than fingernails, it's that toenails tend to be stronger so they don't break as easily. That's why it seems to some people that their toenails are growing faster than their fingernails; Fingernails are more susceptible to breakage because they are thinner.
